CRITICALJenkins Plugin Installation Manager Tool did not verify plugin downloads
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Jenkins Plugin Installation Manager Tool is part of the Jenkins project Docker images. As jenkins-plugin-cli it is used to download and install plugins even before Jenkins is running.
Jenkins Plugin Installation Manager Tool 2.1.3 and earlier does not verify plugin downloads. This may allow third parties such as mirror operators to provide crafted plugin downloads.
Jenkins Plugin Installation Manager Tool 2.2.0 confirms that actual checksums of downloaded plugin match the expected checksums.
Docker images of Jenkins 2.269 and 2.263.1 contain Plugin Installation Manager Tool 2.2.0. Users of older Docker images can change the version they use by extending the Jenkins image and update the tool themselves with:
ARG PLUGIN_CLI_URL=https://github.com/jenkinsci/plugin-installation-manager-tool/releases/download/2.2.0/jenkins-plugin-manager-2.2.0.jar RUN curl -fsSL ${PLUGIN_CLI_URL} -o /usr/lib/jenkins-plugin-manager.jar Jenkinsfile Runner 1.0-beta-22 Docker images also include Plugin Installation Manager Tool 2.2.0.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.jenkins.plugin-management:plugin-management-parent-pom. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update io.jenkins.plugin-management:plugin-management-parent-pom to 2.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-m8r4-c7jm-w782 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-m8r4-c7jm-w782 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-m8r4-c7jm-w782. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-m8r4-c7jm-w782 in your dependencies?
O3 detects GHSA-m8r4-c7jm-w782 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
